Airline profit cycles analyzed with PCA, revealing fewer clusters

By PulseAugur Editorial · [2 sources] ·

A new paper explores the dimensionality and orthogonality of airline profit cycles using Principal Component Analysis (PCA) and Kernel PCA. The research replicates a previous clustering experiment, finding that a six-cluster taxonomy remains geometrically robust across different dimensional spaces. However, the study also reveals that the dataset structurally supports only three clusters, with collinearity in the raw data suppressing this signal. AI

IMPACT This research offers a refined understanding of data structure in complex datasets, potentially improving clustering accuracy in various analytical applications.

RANK_REASON The cluster contains an academic paper detailing a novel analysis method and findings.

    To characterize the US airline profit cycles from 1995 to 2020, the authors of Renold et al. (2023) combine k-means clustering, principal component analysis, and system dynamic modelling. We replicate their clustering experiment in three spaces -- the original 7-dimensional raw-v…
